Specification of` LettersvPatent No. Q91, dated October 26, 1838i.

T0 all whom it may concern Be it known that I,.WILLIAM LEWIS, of the city of New York, N. Y., have invented a new and useful Machine for Constructing Safety-Fuses or Fuses to Convey Fire, in Blasting Rocks and other Substances; and I do hereby declare that the following is a full` and exact description.

The nature of my invention consists in the combination of the reel frame A, Figures 1, 2, 3, and 4, described in the drawings to which this specification refers, and the reels a, a, a, a, &c., attached thereto and secured to the hollow shaft g, and revolving therewith, and in combining with them the cone f and case e, either or both grooved, the whole operating for the purpose of spinning or forming the inner case of the fuse and filling the case with gunpowder. Also in the combination of thereel frame B with the reels Z), b, b, b, &c., with the hollow shaft z, the upper end of which forms a seat or case to thecone y, which cone and seat either or both are grooved for guiding the threads,

fand forming the outer case of the safety fuse;l Also in the, application ofthe rollers grooved for the purpose of compressing the inner case of the fuse, and grooved rollers for the purpose of drawing oil' and determining the length of the fuse.

To` enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

The frame to carry the shafts,&c., shown throughout the drawings may be `made, of wood and of the following dimensions: 5 feet 8 inches in height and'21l inches clear width on each ofits sides; it` has four corner standards, as 2, 2, 2, 2, Figs. 1, 2, and 3 in the drawings. To these standards at the top are xed 4 rails at No. 3,r 1, Nos. 4 and 6,`Fig. 4, and 5, Fig. `3, from 3 to 5 in Figs. 2 and 4, is fixed the bearer 7; at 19 inches lower down on the standardsis fixed 2 rails as 8, Fig. 1, and 10, Fig. 3; from 38 to 10 is fixed thebearer 9, Figs. 2 and 4;, at 18 inches lower down on the standards is `fixed 2 rails, as 11, Fig. 1,` and 13, Fig; 3;

shaft g, Figs. 1, 2, 3, and4, is madeof wrought iron about an inch in diameter, and

bored throughout and lined with brass the hole in the center of the brass` is about of an inch in diameter, the upperend of the shaft. Q. after passing through thel pulley F. is made with a screw to enter the reservoir 7c which screws down tight on the pulley F. Below on the shaftf g, `is fixed the circular block a a, Figs. 2,` 3, and 4; between this block and the frame A, Fig. 4, is placed 6 uprights. 2 onlyof these are shown in section and marked b .6, b Through the block a a, the uprights b b, and frame A is passed 6 bolts `about of an inch in diameter with nuts and screws to secure theframe A. To the liange on the lower end of g is fastened` by screws thestop cock p, Figs. 1 and 4; to the bottom of p is fastened by flanges screwedV together the hollow tube c c, Figs.1 and 4, on the end of c c is formed the grooved cone f, Figs. 4, 7,

and 8, on the cone f is fastened by screws the case e, Figs. 1, 4, 7, `and 8 on the lower end 4of thef case e is formed' a cylindrical tube, shown in section full size by a screw to eachV of the standards, its

weight resting on the circular end of the reel. 12 holes must be `cut through the frame A, Fig. 4, for the lines to pass from the reels a, Va," &c., down to the cone f.. These holes should be lined with metal to keep the wood from wear. The reservoir k,` Figs.` 1,

2, 3, and 4, is made of copper or brass 1n a circular form the upper part cylindrical and Y the lower part funnel shaped inside; to the topa cover is closely fitted, in the center of which a tube is fixed to steady the rod m.

Connected t0 this rod is the plate Z, Fig. 4. This plate isloosely fitted inside le. To the top of m is fixed the arm n suiiiciently long to strike a bell so placed as to be struck4 by therarm n when the plate Z is as low down as it can go in lc. The shaft g revolves in 2 pair ofV journal blocks, one Vpair of which is fixed on the bearer 7, Figs. 2 and 4; and the other pair on the bearer 9. On the nails 11 `and 13, Figs. v1 and 3, are raised the blocks,

Y to adjust and to` confine the lever 7L to the bar g, Figs. 1 and 4, by means of nuts above and below the lever h' the bar g being secured to the standards of the machine; to the shaft ZL ZL is fastened the leverv y', projecting 3 or 4 inches beyond the frameof the machine to carry the weight t', Figs. 1, 2, 3, and 4. To the shafts it 71. and z' z', Fig. 4, is fixed the rods j j, j y', each having a slot in the lower end to receive a brass friction roller, as shown in F 4, marked CZ, c, and the edge of Z isV seen in Fig. 2. These rollers are grooved on the edges according to section Fig. 6. The circular frame B, Figs. 2 and 4, with the standards, reels and drags are eX- actly like those of A, Figs. 1, 2,3, and 4 and 'already described; in the center of frame B is a circular hole cut large enough to clear the threads from the reels Z9, Z), Z),

&c., as they pass into the hollow shaft L, which is made of brass and boredout to let the fuse pass free. L is firmly screwed to the under side of B; the upper end of Lis turned out to an angle of about 45 degrees and grooved to admit the threads from the `reels Z9, Z9, Z9, Sac., passing freely intorthe center of L; on the conical seat so formed in L the cone y, Fig. 4, is fitted. y is bored vertically in its center to let theV fuse pass free. The cone y is held in its place'by 2 screws tapped into L. The outside of L is turned and an iron or steel collar fitted thereto. This collar is screwed down to the bearer 12, Figs-2 and 4. To the under side of 12 is fastened the hanging bracket lo, la, having a hole for L to run in; in the space between the bearer 12 and the bracket 1c k, on L, is. fastened the pulley G, Figs. 1, 2, and 4. On the bearers 18 and 17, Fig. 5, 18, Figs. 1 and 5, is placed the frame w, Figs. 1, 4, and 5. This frame can be moved on the pin ZakFig. 5. On w is placed a shaft running in journal blocks and carrying the grooved roller u and the pulley w Figs. 1 and 5. To thev bearer 17, Fig. 5, is fixed the loaded lever o, acting againstthe frame w at Z Z. bearer 18,`Figs. 1,2, and 5, and the rail 16, Fig. 3 is placed a shaft carrying the grooved roller and the pulley m F igs.v 1, 2, andV 5, withl the large pulley I, Figs. 2 and 3. The rollers u, u, are grooved according to section,

Fig. 6. On the blocks f f, Fig. 1, and g g,

Fig. 3 is'placed a shaft carrying the pulleys H and J, Figs. 2 and 3. On the railsS, Fig.

1, and 10, Fig. 3,*'is placed a shaft running in journal blocks and carrying the pulley D andthe crank C, Figs. 2 and 3; also the pulley E, Figs. 1 and 2. On the Vrails 13l On VJthe and 11 is placed thel blocks Z, Z, Z, Z, Figs. 1 and 2 each'block having a slot'cut in its end to Vadmit a friction roller for the lines from E to pass over to pulleys F and G. A mortise is also cut in each block for a screw to pass to hold the block in its place. VOn the standards as shown in Fig. 3 and partly in Fig. 2 is fixed the loaded lever Ii by a pin at m, m. To the lever K, the arm, 1L, n, is fastened to carry the friction roller 0 0. The lever K plays up or down in a mortise cut in p p. Near the bottom of one of the standards at g g, Fig. 3, is fixed by a pin the lever L, to the upper end of which is Xed cut so as to allow the 'lever t t to rise and fall. The pulleys, D, H, I, J, 0 0,and s s, Figs. 2 and 3, are grooved to suit such belts or lines as may be chosen to drive these pulleys. The pulleys E, F, Gr, and w have Vgrooves cut on them with a small square groove cut at the bottom of each V groove to eep the V groove from clogging. A piece of spring tempered steel about the thickness and width of such as is used for the main spring ofa watch is held by a button or screw on the top of Veach of thestandards, fixed in the frame B, Figs. 2 and 4, to press on the drag which rests on the end of each of the reels shown in Figs. 1,v 2, 3, and 4. The top of the standard marked b Z) and the drag marked e e with the button marked Q) fu,

Vand the spring marked lfw fw, is shown full size in Fig. 9. The diameters of the several pulleys shown throughout the drawings may be taken as follows:V The pulley E, Figs. 1 and 2, 21 inches; D, Figs. 2 and 3, 54 inches; H, Figs. 2 and 3,l 21 inches; J on H at 6 inches; I, 12 inches; the cone of pulleys F, at 5, 6 and 7 inches; the cone of pulleys Gr the same as F; the rollers u u, 4 inches diameter; the pulleys w and m, 211,` inches; thel friction rollers d and c, F ig. 4, one inch in diameter; the frictionprollers o 0 and s s, about 3 inches in diameter. Y

The operation of making safety fuse by my machine is as follows:V Having filled the reservoir is with gunpowder and filled the reels with thread, bring the threads from the reels a, a, a, a, through the holes in the reel frame A, Figs. 4, 3, 2, and 1, take the case e from off the cone f, then pass the threads along the grooves in the cone f, twist the threads together and pass them through. the case e, secure the case e on the cone f, raise the cone y from its seat in Z, pass the twisted threads through the hole in the center` of y, bring the threads from Vt-he reels Z), ZJ, Z9, Z, pass them with the cone y, and secure it'down toits seat in L.

The whole of the threads Vis then brought down between the grooved rollers u, u, adjust the grooved roller c to the twisted threads by the nuts and screw at g, press the roller Z against the twisted threads by the weight i on the lever j, open the stop cock p, put the reel frames in motion by driving the crank handle C. The safety fuse is then made. The fuse is afterward coated with water proof varnish to keep the powder dry. Y

In the machine represented by the drawings the power is applied to the crank C. This puts in motion the pulleys D and E; the pulley E drives the pulleys F and G, the pulley F drives the shaft q with the frame A, the pulley G drives the hollow shaft L with the frame B in contrary direction to that of A, the pulley D drives the pulley H, attached to which is the pulley Y. This drives the pulley I, the shaft of which carries one of the grooved rollers u and the pulley m, the pulley a? drives the pulley w, m with the other grooved roller u. The loaded levers K and L with friction rollers are used to tighten the belts or lines on pulleys I), H, I, and J. The movable blocks Z, Z, Z,

are used to guide and t0 tighten. the lines when the reservoir lo requires refilling with gunp owder.

What I claim as my invention and "desire,

to secure by Letters Patent is-' 1.- The combination of the reel frame" and j reels with the hollow shaft, cone and case,

for making the inner case of the fuse, and in combination with them the grooved roll- Y ers for compressing the inner case.

. 2. the combination of the reel frame and the reels and hollow shaft withthe cone and case'for the purpose and making and putting on the outer case of the safety fuse and in combination with them the grooved rollers for drawing off and determining the length o-f the fuse, the whole being constructed and operating in the manner substantially as herein described. i
